So if you are using Prism, then you should be using the Prism container.  I think Prism 7 had an Autofac version, but they depreciated that. starting at Prism 8.  I would suggest Prism.DryIoc as that is the direction they are moving with Prism 9.  You want to add one of the Prism packages with a container either Prism.Unity or Prism.DryIoc and then let Prism do the rest Prism provides a method in App.Xaml.cs to override with registrations.  protected override void RegisterTypes(IContainerRegistry containerRegistry) { containerRegistry.Register<IComboBoxItem, ComboBoxItem>(); containerRegistry.Register<IToolbarCommand, ToolbarCommand>(); containerRegistry.RegisterSingleton<IConnectionCheck, PortalConnectionCheck>(); containerRegistry.RegisterSingleton<ILog4NetFacade, Log4NetLogger>(); //If you did not have Modules or Regions you could register a view for Navigation here containerRegistry.RegisterForNavigation<MobileAppMapView, MobileAppMapViewModel>(); }  If you have Modules the initialization is done in the IModule implementation and would be along these lines /// <summary> /// Map Module is primary application module responsible for inital loading /// of the map and all interations with the MapView /// </summary> public class MapModule : ModuleBase // I have a ModuleBase class that implements IModule so that common initialization code is put there { public override void RegisterTypes(IContainerRegistry containerRegistry) { base.RegisterTypes(containerRegistry); containerRegistry.Register<IMapLoadService, MapLoadService>(); } public override void OnInitialized(IContainerProvider containerProvider) { base.OnInitialized(containerProvider); //RegionManager comes from base class this is is how one gets RegionManager in Module // RegionManager = containerProvider.Resolve<IRegionManager>(); RegionManager.RegisterViewWithRegion(RegionNames.MapRegion, typeof(MobileAppMapView)); } } There is no need to be setting a DataContext, Prism does that for you As an aside:  I would avoid naming my View MapView, I find this confuses things sometimes because it is the same name as the esri class ...
